हिन्दीWhich of the following pairs of orbitals will experience the larger effective nuclear charge in a multi-electron system?
Correct answer · Option 3
\( 3d \) and \( 3p \)
Explanation
Penetration power decreases in the order \( s > p > d > f \). Orbitals with higher penetration experience less shielding and thus a larger effective nuclear charge (\( 3p > 3d \)).
